What at first appeared to be a satellite shoots straight towards me at high speed, then reverses direction back to where it had been.I was sitting in a lawn chair looking up in the night sky not long after dark, when I spotted what I thought was a satellite to the east of me. I noted that it was about the same brightness as the surrounding stars except that it was moving across the sky at the speed of the usual satellite in a SW direction. When it was aligned in front of and above me, at about 95-100 degrees, it appeared to suddenly shoot straight down towards me at a high rate of speed growing larger and brighter (bright white) the closer it came, maybe to about 10x the size it had been, not any larger than a dime. I thought to myself that if it continued in that direction it might hit me. Then about ½ way down it suddenly reversed direction and went back up to the approximate altitude that it had been, continuing on its course in approximately the same SW direction. The up and down trajectory lasted not more than a second or two. A friend of mine was walking towards me, from behind, whe! n I exclaimed, Whoa! in regard to the object coming towards me. He did not see the object until I pointed it out after the fact. So what he saw looked like a normal satellite traveling across the night sky. We watched the object as it continued SW with no more unusual activity. So what was the object: a military hologram, an ET spacecraft, something going on with my eyes (doubtful), or what?((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
